Description

[Detailed description of the invention] The present invention relates to a reaping and conveying device for a combine harvester, and in particular, during combine harvester work, the culm is pulled up by a pulling device, is held and conveyed by a front conveying device, and then cut by a cutting blade, and then cut in a lateral direction. The present invention relates to a reaping conveyance device configured to convey the grain to a threshing device and supply it to a threshing device.

By the way, a device in which a lifting device, a front conveyance device, and a lateral conveyance device are provided from the front has been devised in Japanese Utility Model Application Publication No. 144726/1983.

However, in this device, the starting end of the front conveyance device is positioned above the cutting blade, so the planted shell culm pulled up by the pulling device is cut by the cutting blade and then transferred to the front conveyance device. Since the culm is transported backwards, the heavy tip part hangs down and the culm posture is disordered, which has the disadvantage that it cannot be transferred to the horizontal transport device in an orderly manner.

The present invention solves these drawbacks, and uses a front conveyor device installed diagonally at a high rear position between the lifting device and the upper part of the cutting blade to transport the tip of the planted culm raised by the lifting device. The culm is carefully conveyed to the rear while maintaining good culm posture.
It is an object of the present invention to provide a reaping conveyance device that eliminates disturbances in the posture of grain culms by transferring grain culms to a horizontal conveyance device almost simultaneously with reaping, and that also ensures good transfer from the horizontal conveyance device to a vertical conveyance device/feet chain. shall be.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a perspective view of the entire combine harvester, in which a threshing device 5 is mounted above the track-type traveling body 7, and a reaping and conveying device supported by a frame 8 etc. is installed at the front of the machine body in front of the device 5. This device has a three-row mowing structure with four grass dividing boards 9 arranged in parallel at the frontmost part, and at the rear thereof, a mowing machine consisting of three tilting mowing cases each having a tine 1. A lifting device A is installed, and the structure is configured so that two culms can be pulled up between the two pulling devices A on the left side through one culm layer using the pulling device A on the right side. .

In addition, there are tine 3 behind each of the three lifting devices A.
Two front conveyance devices B with
Guide plates 10 and 10 are provided opposite to H so that the upper side of the culm can be held and conveyed by the tines 3.

A horizontal reciprocating type cutting blade 2 is installed below the rear end side of both front conveyance devices B, and a shell facing the rear end side of both front conveyance devices B and B is installed above the cutting blade 2 toward the rear. A substantially triangular-shaped tine 11-type horizontal conveyance device C9C having a horizontal feed path for conveying the culm to the side of the machine body and a vertical feed path for conveying the culm to the rear of the machine body is installed approximately parallel to the front conveyance devices B and B in side view. A vertical conveying device 4 is installed across the vertical feeding path of the horizontal conveying device C and the starting end of the foot chain 6 of the threshing device 5, and the vertical conveying device 4 clamps the culm side of the shell culm. It is configured so that it can be raised to a horizontal position and fed to the starting end of the foot chain 6 of the threshing device 5 as it is.

Therefore, during combine harvesting work, the three culms separated by the weed cutting board 9 are pulled up by each lifting device A in the planted state, and then the two front conveying devices B and B are engaged by the tines 3 of B. The culm posture is controlled by feeding, and the culm is conveyed while combing and elongating the tip part so that the primordial tip side is not delayed.The culm side of the culm is reaped by the cutting blade 2 everywhere at the end of the front conveying device B, immediately after reaping. Next, the top and bottom of the culm are locked by the horizontal feeding path of the horizontal feeding device C2C, and while conveyed in the horizontal direction, the three strips are merged, and the vertical feeding device 4 takes over the culm base side in the vertical feeding path, and the culm is conveyed as it is. The culm is made horizontal without raising the base side, and the threshing device 5 is inherited by the foot chain 6.
supply to.

As described above, in the present invention, the front conveying device B in the front and back direction, which pinches and conveys the upper side of the culm with the tines 3, is shown in side view between the pulling device A having the tines 1 and the upper part of the rear cutting blade 2. The cutting blade 2 has a substantially triangular shape having a horizontal feeding path for feeding the cut husk to the side of the machine body and a vertical feeding path for feeding it to the rear of the machine body on the rear side of the cutting blade 2. The lateral conveying device C is provided approximately parallel to the front conveying device B in a side view and in two stages, upper and lower, and the culm joint position between the terminal end of the front conveying device B and the starting end of the lateral conveying device C is arranged approximately directly above the cutting blade 2. Furthermore, since the vertical conveying device 4 is provided across the vertical feeding path of the horizontal conveying device C and the starting end of the foot chain 6 of the threshing device 5, the tip of the planted husk culm pulled up by the lifting device is moved backward. The culm is combed out by the front conveying device B installed obliquely at the height of the throat, and is surely conveyed backwards while maintaining a good culm posture, and the culm is handed over to the horizontal conveying device C almost at the same time as cutting with the cutting blade 2. This makes it possible to eliminate disturbances in the culm posture in this area.

In addition, since the upper and lower two-stage horizontal conveyance device C is installed approximately parallel to the front conveyance device B in side view, the upper and lower sides of the culm can be securely locked without causing conveyance holes or pulling or cutting of the culm. is transferred from the front conveyance device B to the lateral feed path of the lateral conveyance device C,
Furthermore, since the starting end of the vertical conveyance device 4 faces the vertical feed path of the horizontal conveyance path C, the husks can be fed to the threshing device 5 in an orderly manner.
